Image management

[Markus Gothe]

For Sierra W Devices this gives a hint: https://github.com/jasonswan/uconnect-swdl/blob/master/RA4/usr/share/scripts/update/installer/sierra_wireless.lua

One have to issue AT!BOOTHOLD (in Supervisor a.k.a A710-mode???).

The QDL-thing seems scary as we don’t have ANY documentation about it that’s not based on a NDA.
AFAIK this goes for USSD as well (which is part of the ‘voice’-service).
